Thanks for the replies.

So, I'm thinking about making a harness/balancer for the balancer for the previous mentioned plug.

Does anyone see the problem with getting a 6s harness for the balancer and a JST-XH balance board and cut the useless end off the harness and the useless end off the balance board and put the balancer side of the harness and balance board side harness together in the right configuration?

Or even a 2s flightpower harness, cut the highrate end off and put a normal JST-XH plug on in the right configuration?

As for the picture I have posted above, the wires are coloured:
(top 2 pics, L-R) Red, Blue, Black.

Does anyone know what the order is on the flightpower balancers so I can get them right?

Or would the blade one posted above actually work for this?

Cheers.
